Abstract: An aggregate bin heater assembly having a bin for receiving aggregate therein and a plurality of fluid inlets supported at vertically spaced apart elevations relative to the bin for distributing a heating fluid into the aggregate within the bin, further includes a control system for controlling distribution of the heating fluid. A pressure sensor associated with at least an uppermost one of the fluid inlets so as to be arranged to sense pressure within the bin at the respective elevation. A controller determines a low pressure condition if the pressure sensed by the pressure sensor is lower than a prescribed normal pressure. A valve associated with the uppermost one of the fluid inlets shuts off the flow of heating fluid to the uppermost one of the fluid inlets responsive to determination of the low pressure condition by the controller.

Abstract: In reagent reaction experiments using microplates, the operator cannot just set dispensing tips in all the fixing holes of the dispensing tip container. It is necessary to carry out the time-consuming task of deciding in advance on a suitable arrangement of positions for the dispensing tips. It is also necessary for the operator to carry out the time-consuming task of determining in advance the quantity of reagent used and how the reagent is to be arranged. These problems are solved by providing a control device that includes a dispensing tip arrangement calculator and reagent quantity and arrangement calculator, and that can inform the operator of these results. The dispensing tip arrangement, the reagent quantity used, and the reagent arrangement is calculated from the information set in advance on specific reagent, the quantity of reagent dispensed into one well of the microplate, the range of wells in the microplate into which reagent is dispensed, and the direction of dispensing.

Abstract: The invention relates to a device for portioning flowable food products, consisting of: a first group of cylinders (1) comprising pistons (3) which communicate with a chamber (5) having an inlet (5a) and an outlet (5b); a second group of cylinders (2) comprising pistons (4) which communicate with a chamber (6) having an inlet (6a) and an outlet (6b), and dispensing means. Said dispensing means are controlled by synchronisation and control means in order to: alternately communicate a food product inlet (9) with said chamber (5) whereby the cylinders (1) open the inlet (5a) and close the outlet (5b) thereof; and simultaneously communicate an outlet (10) with said chamber (8) whereby the cylinders (2) close the inlet (56a) and open the outlet (6b) thereof and vice versa. Fluid dynamic cylinders (26) actuate each piston (3, 4) consecutively or actuate on sub-groups of pistons (3, 4) consecutively in order to empty the cylinders (1, 2).

Abstract: A multi-component proportioning system for dispensing a multi-component coating composition is provided. The delivery system is particularly useful in providing multi-component compositions to a multi-component dispenser. The system provides very accurate mix ratios due to the consistent, reproducible displacement of components from the liquid pump assemblies used in the multi-component proportioning system regardless of viscosity. Such accuracy eliminates improper mixing of components that can lead to reworking and lost time, materials, and profits.

Abstract: A dispensing package such as a grease cartridge is made up of a one piece tubular cartridge body and a puncturing end cap. One end of the cartridge body is open and the other end has an imperforate endwall formed with an annular severing zone which surrounds a central cut out panel. The end cap is formed with an interiorly disposed puncturing structure and is adapted to close off the open end of the filled cartridge body. To ready the cartridge for dispensing as in a grease gun, the end cap is removed from the cartridge open end and reapplied over the cartridge closed end. The end cap is then employed to pierce the severing zone of the cartridge endwall and effect removal of the central cut out panel.

The conveyors each comprise an endless belt which, through further belts, rotate the spreader members about vertical axes. Disposed between each spreader and the end of the corresponding conveyor is a guide hood which guides the flow of material to the rotary disc behind its flat ejector blades which are biased 60.degree. from a radial line intercepting the inward edge of the blade, so that at design speed the material is ejected through an arc of about 180.degree..

Abstract: The dispensing apparatus includes a syringe having a plunger therein and appropriate inlet and discharge openings associated therewith. Two cams are positioned in spaced relationship with a connecting rod mounted to an eccentric of each cam and pivotally to the plunger in the syringe. Motor elements cause rotation of one of the cams with the second cam acting as the fixed pivot point to move the plunger through a first distance. Rotation of the second cam with the first cam acting as the fixed pivot point causes the plunger to move through a second distance. Two liquid volumes are, therefore, dispensed from a single syringe in which one-half cycle of rotation of either cam acts to fill the syringe and the other half cycle acts to discharge the syringe. A multistation dispenser is provided by using a plurality of syringes and connecting two such cam assemblies to a cross bar which causes simultaneous reciprocation of the various plungers associated with the plurality of syringes.
